What the number itself says

Reading SEGLX.143DB1 left to right: S is the model-year letter for 2025, EGL is the three-character code the EPA assigned to Egl Motor as certificate holder, X marks an off-road certification, .143 is the displacement in litres, so 143cc and DB1 is Egl Motor's own sequence for that year. Nothing in the number names the factory — that comes from the certificate itself.

The engine, as described on the certificate

The test vehicle Egl Motor submitted for this family (model A13) carried engine code ZS1P56YMJ. In the Chinese engine-model convention that reads as one cylinder, horizontal (flat) cylinder, with a nominal 56 mm bore, YMJ series.

The certificate describes a four-stroke, single-cylinder engine with 2 valves per cylinder fed by carburettor. No catalytic converter is listed.

Rated power on the record is 8.8 kW (about 12 hp) at 8,500 rpm, driving through a 4-speed manual gearbox.

Filing history and where it was sold

Egl Motor filed one certificate under this family, for model year 2025, sold as both a 50-state and a 49-state version.

The vehicle itself is recorded as built by the same company, Yongkang Eagle Motor Co., Ltd. in China — engine and chassis from one source.

Certified emission levels: CO 5, HC+NOx 1.2 g/km.

Other records carrying the same engine code

Egl Motor certified an engine with this code under 4 other family numbers — the same engine filed again in another year, or in an off-road and a street version:

• NEGLX.143DB1 (2022)
• PEGLX.143DB1 (2023)
• REGLX.143DB1 (2024)
• TEGLX.143DB1 (2026)

A shared code from the same factory is a strong search lead. From a different factory it is as often a naming coincidence. Either way it narrows the search; it does not settle it — measure before you buy.
